A diagnostic complex has been developed for the modelling and experimental investigation of the gas-dynamic and spectral characteristics of an inductively coupled plasma. This complex includes a four-dimensional computer model of plasma, a research plasma generator, a schlieren system for visualizing the spatial structure of gas flows in the torch, and a high-resolution spectrometer for obtaining information on the temperature in the discharge zone from the intensity of the emission spectra. The model adequately maps the gas-flow dynamics in the torch with no discharge ignited in the inductively coupled plasma. The results of the calculations agree well with the experimental data.
